msg.obj cannot be resolved or is not a field

Question

今天SVN了一个项目，打开发现好多包没加载，加载完成后出现了cannot be resolved or is not a field，不知如何做了，代码如下
其中msg.what msg.obj都提示cannot be resolved or is not a field。

 public  class AlarmCfgHandler extends Handler {
          public AlarmCfgHandler(Looper looper) {
              super(looper);
          }
          public void handleMessage(Message msg) {

              switch (msg.what)
              {

                case comm_frame.SYS_CFG_RSP_FRM: 
                    sys_cfg_rsp sys_cfg_rsp_info;
                    sys_cfg_rsp_info = (sys_cfg_rsp)msg.obj;
                    if(sys_cfg_rsp_info.child_type == comm_frame.SYS_CFG_TYPE_ALARM)
                    {

                        new AlertDialog.Builder(ctext).setTitle("完成")
                        .setMessage("报警设置成功")
                        .setPositiveButton("确定", null).show();
                    }
                    break;
            case  comm_frame.EVENT_RSP_FRM:
                event_info_rsp_class event_info_rsp;
                event_info_rsp = (event_info_rsp_class) msg.obj;
                comm_frame.invokeLongTimeToast(event_info_rsp, ctext);
                break;
              }
          }
     }
